Authenticate a user.

The first argument is a JSON object containing information for authenticating the user. What this actually contains
depends on the specific implementation. In the case of a simple username/password based
authentication it is likely to contain a JSON object with the following structure:
  {
    "username": "tim",
    "password": "mypassword"
  }

For other types of authentication it contain different information - for example a JWT token or OAuth bearer token.

If the user is successfully authenticated a  object is passed to the handler in an .
The user object can then be used for authorisation.
